The stout trading brig Amity, Samuel Mudge master and part owner, was gliding up Plymouth Sound on a summer's evening towards her accustomed berth in Catwater, a few years before the termination of the last war between England and France. She had no pilot on board; indeed, her crew averred that the old craft could find the way in and out of the harbour by herself; at all events, her master knew it better than most men trading from the port, as did his young mate, Ralph Michelmore.
